Abstract: A knife assembly includes a handle having a first and second handle portion each extending in spaced relationship with one another between a first and second knife end to define a working gap. A knife blade is pivotably secured to the second knife end and pivotable between a closed and engaged position. A switch button is interconnected to the handle for releasing the knife blade from the closed or engaged positions. A spacer is disposed within the working gap and extends between the first and second handle portions. A vial of tritium is housed within the switch button for allowing tritium produced by the tritium vial to be viewable by a user of the knife assembly.

Abstract: A safety selector for switching a firearm between at least two firing modes. The safety selector includes a cavity for placing a vial of tritium to provide a visual indication of the selected firing mode. A lock member extends through a portion of the firearm to regulate movement of a firing mechanism. A lever arm and a faceplate are connected to one end of the lock member to rotate the lock member between positions and an endcap is connected to the opposite end of the lock member to rotate therewith. At least one of the lever arm, the faceplate, and the endcap define the cavity for nesting the tritium vial. Another lever arm and faceplate may be located on the other side of the lock member for ambidextrous usage. The additional lever arm and/or faceplate may also include a cavity for nesting another tritium vial.

Abstract: A tritium housing includes a body extending from a first end to a second end to define a hollow extending therebetween. A lens is disposed adjacent and surrounded by the first end of the body and a tritium vial is disposed within the hollow to produce illumination visible through the lens. The body is comprised of a colored plastic material for magnifying and brightening the tritium illumination during a daylight use of the tritium housing.

Abstract: A thumb stud for a folding knife assembly includes a body extending between a first end and a second end. A hollow passage extends between the ends, and a tritium vial is disposed within the hollow passage and extends between the first and second ends. A first lens is disposed within the hollow passage adjacent the first end and a second lens is disposed within the hollow passage adjacent the second end. The first and second lenses encapsulate the tritium vial within the hollow passage of the body and allow illumination produced by the tritium vial to be viewable through the first and second lenses to illuminate the thumb stud. In an alternative arrangement, the tritium vial can be replaced with a wafer which houses the tritium vial. In this arrangement, a pair of wafers are each disposed adjacent respective lenses at respective ends of the body.
